Adding Write Arb API and system tests and misc fixes

[vnktshr21]

• This contribution adheres to CONTRIBUTING.md.
• I've updated CHANGELOG.md if applicable.
• I've added tests applicable for this pull request

What does this Pull Request accomplish?

• Enables write arb waveform API
  • Adds a fancy function which supports multiple complex datatypes and calls into the appropriate interpreter method based on incoming waveform datatype
  • Implementation follows nifgen write_waveform fancy function pattern (nifgen has the exact same use case)
  • This fancy function would also allow adding more complex datatypes support in future if required, with one single public write_arb_waveform function supporting all of it
  • Doc tip and function description for fancy function is tweaked to call out the supported datatypes
• Adds system tests for all the important supported API
  • Some tests can run only on real hardware and are skipped based on a single flag
• Adds arb and script mode examples
• Examples and system tests are now put through flake checks
• For set, get burst start, burst stop and marker event location APIs
  • Fixes the size parameter behavior
  • Fixes the datatype of locations
  • Marks channel name parameter as repeated capability with appropriate repeated capability type field value set
• Changes reset function case to match the header case
• Adds correct enum for parameter of configure power level type and digital trigger edge functions
• Self cal last date time function gets a module parameter matching the C API
• Removed unnecessary tabs and line breaks in some of the documentation
• Fixed the option string parameter handling for initialize
  • Metadata was missing template specification in rfsg

List issues fixed by this Pull Request below, if any.

None

What testing has been done?

• New write arb waveform API(all datatypes) are tested to be functional with real hardware
  • Correct signal generation verified with Analyzer
• All system tests pass on both real and simulated hardware
  • Fixes for function parameters across multiple functions are all tested as part of system tests
• All examples run fine on both real and simulated hardware
• Documentation improvements are visually inspected

Can you include a justification for the fancy function in your PR description?
I think you're probably right to create it, but it would be nice to have the thought process written down for posterity, if it's not too much trouble.
